Benefits of technology

[0006]It is an object of the present invention to provide a novel toner supplying container, which reliably prevents the leakage of the toner contained therein before it is mounted on a mounting member, or after it is removed therefrom, or at the time of being attached or detached, which is constituted by a decreased number of parts enabling the cost to be decreased, which as a whole can be constituted by using synthetic resin members only without at all using metallic parts, and which can be disposed of without requiring sorting operation.

Problems solved by technology

The above toner supplying container, however, requires an urging spring portion or, specifically, a metallic tensile coil spring, which is a separate member, for urging the lock lever portion, resulting in an increase in the number of parts and in an increase in the cost.

Embodiment Construction

[0031]Preferred embodiments of a toner supplying container constituted according to the present invention will now be described in further detail with reference to the accompanying drawings.

[0032]FIG. 1 is a sectional view schematically illustrating the constitution of a tandem-type color image-forming machine equipped with a developing device on which are mounted toner supplying containers constituted according to the present invention. The illustrated tandem-type color image-forming machine is provided with an image-forming machine body 200 of nearly a rectangular parallelopiped shape. In the image-forming machine body 200, there are arranged a process unit 202 for black, a process unit 204 for cyan, a process unit 206 for magenta, and a process unit 208 for yellow in this order from the left toward the right in FIG. 1. The process units 202, 204, 206 and 208 are each equipped with image-forming elements such as a photosensitive material drum 210, a charging unit 212, an LED head ...

Abstract

A toner supplying container has a container body having a toner discharge opening, a shutter member, a lever member, and a locking member. The lever member at its closing position causes the elastic portion of the locking member to be elastically deformed to urge the locking member to the locking position. When the container body is mounted on the image-forming machine body, the locking member is displaced to a lock-releasing position, permitting the lever member to be turned from the closing position to the opening position.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a toner supplying container used for supplying a toner to a developing device provided for an electrostatic image-forming machine such as a printer, a copying machine or a facsimile.DESCRIPTION OF THE RELATED ART[0002]A toner is contained in a toner supplying container (toner supplying cartridge) used for supplying the toner to a developing device provided for the above-mentioned image-forming machine. After the toner supplying container containing the toner is mounted on the developing device or on the image-forming machine body, which is a mounting member, a toner carrier screw housed in the toner supplying container is rotated. Therefore, the toner held therein is discharged through a toner discharge opening and is supplied into the developing device.[0003]It is not desired that the toner contained in the toner supplying container leaks to the outer side, before the toner supplying container of the form described above ...
